Sorption

Physical or chemical process by which one substance becomes attached to another

Sorption
Summary

Physical or chemical process by which one substance becomes attached to another

Gas–liquid absorption (a) and liquid–solid adsorption (b) mechanism. Blue spheres are solute molecules.

Sorption is a physical and chemical process by which one substance becomes attached to another. Specific cases of sorption are treated in the following articles: ; Absorption: "the incorporation of a substance in one state into another of a different state" (e.g., liquids being absorbed by a solid or gases being absorbed by a liquid); ; Adsorption: The physical adherence or bonding of ions and molecules onto the surface of another phase (e.g., reagents adsorbed to a solid catalyst surface); ; Ion exchange: An exchange of ions between two electrolytes or between an electrolyte solution and a complex.

The reverse of sorption is desorption.

Sorption rate

The adsorption and absorption rate of a diluted solute in gas or liquid solution to a surface or interface can be calculated using Fick's laws of diffusion.
